摘要: 以进口朱顶红栽培品种双龙(Hippeastrum hybridum ‘Double Dragon’)幼苗为试验材料,研究不同浓度的水杨酸、赤霉素、萘乙酸3种生长调节剂对朱顶红幼苗球茎大小、叶片生长、叶绿素含量和根系生长等的影响。结果表明,在不同喷施频率下,合理的喷施生长调节剂(水杨酸和赤霉素)能够显著地促进朱顶红幼苗的叶宽、叶长、球茎等的生长,其中喷施100 mg/L水杨酸6次左右效果最佳。喷施3次水杨酸和赤霉素能显著提高叶绿素含量,其中赤霉素对促进朱顶红叶绿素含量增加最为明显。适宜浓度(50 mg/L)的萘乙酸对促进朱顶红的根系数量增加效果最为明显。

Abstract: The effects of different concentrations of three growth regulators salicylic acid, gibberellin and naphthalene acetic acid on the bulb size, leaf growth, chlorophyll content and root growth of the seedlings of Hippeastrum hybridum ‘Double Dragon’ were studied. The main results were as follows:the rational spraying of growth regulators(salicylic acid and gibberellin) promoted the growth of the leaf width,leave length and the bulb, and the effect of spraying 100 mg/L salicylic acid about 6 times was the best. Spraying salicylic acid and gibberellin 3 times significantly increased the chlorophyll content, of which gibberellin was the most obvious. The optimum concentration (50 mg/L) of naphthalene acetic acid was the most significant factor in promoting the root number of the seedlings.

Key words: Hippeastrum hybridum, seedling, growth, growth regulators
